please answer!

Given:

Frequency distribution table.

Mode = 34.5

To find:

The value of missing frequency 'f'.

Solution:

Formula for mode is

where, l is lower limit of modal class, is frequency of modal class, is frequency of preceding class, is frequency of succeeding class, h is class size.

Mode is 34.5, so the modal class is 30-45. So,

Putting these values in the above formula, we get

Divide both sides by 15.

Separating variable terms, we get

Divide both sides by -0.4.

Therefore, the value of f is 10.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
